Title: Method of and apparatus for analyzing degrees of granule grinding
Inventor: SATAKE TOSHIHIKO
IPC: G01N21/85
Filed: 1991-11-22
Granted: 2000-04-04
Abstract: A method of analyzing degrees of granule grinding includes steps of: passing granules between a coherent-light emitter and a light receiver directly receiving a coherent light emitted from the coherent-light emitter; measuring the time of each of the granules intercepting the coherent light, and the frequency of such interception; and, analyzing the measured granules by arithmetically-processing the intercepted time, frequencies and predetermined coefficients. An apparatus for carrying out such method includes a passage for granules to pass through, and to intercept, the coherent light between the coherent-light emitter and the light receiver, a counter for counting from outputs of the light receiver the interception time of the granules passing at the passage, a memory for storing outputs of the counter, frequencies of each of such output values and predetermined coefficients, and arithmetic operator for conducting calculations based on the information stored in the memory. This apparatus for analyzing degrees of granule grinding can be advantageously incorporated in a granule grinder for its roll-space adjustment.

Abstract: A gamma camera usable for measuring the attenuation factor of gamma radiation in a body being examined is made from a gamma camera customarily used to examine the effects of gamma radiation emitted by markers injected into the body. To this end, the collimator (18) of the gamma camera is removed and replaced by a ring (17) and an arm (13) to which is secured a box (12) designed to contain a point-like radioactive source (11) outside the body. It is shown that transmitted images may thus be obtained very quickly. These images may be used to correct normal emission images.

Patent CA-2072345-C (CA)
Inventor: TYMES LAROY
IPC: H04L12/56
Filed: 1992-06-23
Granted: 2004-05-04
Abstract: A packet data transmission system is used to link a number of remote hand-held data-gathering units such as bar code readers to a central computer which maintains a database management system. Data packets are sent from the remote units by an RF link to intermediate base stations, then sent by the base stations to the central computer by a serial link. Direct sequence spread spectrum modulation is used for the RF link. The remote hand-held units initiate an exchange using RF transmission to and from the base stations, receiving only during a rigid time window following a transmission from the remote unit. The base stations cannot initiate communication to the remote units, but instead send data to the remote units only as part of the exchange.

Title: Apparatus and method for recording digital video signals
Inventor: KANOTA KEIJI
IPC: G11B5/09
Filed: 1992-07-13
Granted: 2002-09-17
Abstract: In a digital VCR having a plurality of magnetic heads for recording digital video signals in slant tracks on a magnetic tape, a recording circuit divides a digital input video signal into data blocks and performs an orthogonal transformation, such as the discrete cosine transform, in order to compress the data.      The resulting blocks of coefficient data are recorded so that all coefficient data of a given block are recorded together by one of the magnetic heads on a single track. In this way, propagation of errors caused by head clogging or drop-outs is prevented.

Granted: 2003-07-15
Abstract: La mesure des niveaux successifs d'un signal reçu est effectuée en combinant entre eux les éléments de groupes d'échantillons numérisés qui sont prélevés sur le signal durant des fenêtres d'échantillonnage successives positionnées par une horloge locale maintenue bien synchrone avec le signal. La combinaison consiste en une moyenne pondérée de manière à tenir compte des conditions de transmission: bande passante de la voie, débit requis, bruit de fond etc, susceptibles de déformer les signaux transmis et donc d'entraîner des erreurs sur la mesure de leurs niveaux réels. Pour mener cette pondération à bien, on utilise les mots numériques d'un même groupe pour adresser une mémoire où l'on a rangé au préalable les valeurs qu'il convient de choisir pour chacun d'eux..   Application à la mesure de signaux codés à niveaux multiples par exemple.

Title: Carrier regenerating device correctly operable in mobile satellite communication
Inventor: IWASAKI MOTOYA
IPC: H04L27/00
Filed: 1993-02-16
Granted: 1997-12-23
Abstract: Supplied with an input signal into which a carrier signal is modulated at a frame period by a data signal and unique words periodically interspersed throughout the data signal, a demodulating circuit (14) demodulates the input signal into a demodulated signal.          A frame synchronizing circuit (23) produces an aperture signal which defines an aperture interval determined by the frame period when the demodulated signal has a level which is lower than a predetermined threshold level.          Responsive to the aperture signal, a cross-correlating circuit (24) calculates a cross-correlation coefficient between the demodulated signal and a locally known unique word.  By the use of the cross-correlation coefficient, a phase error calculating circuit (25) calculates a phase error between a reproduced carrier signal reproduced from the demodulated signal and a regenerated carrier signal which is a correct regeneration of the carrier signal.          By the use of the cross-correlation coefficient and the demodulated signal, a frequency error calculating section (31-35) calculates a frequency error between the reproduced carrier signal and the regenerated carrier signal.  A carrier regenerating circuit (15) makes the reproduced carrier signal become the regenerated carrier signal in accordance with the phase error and the frequency error.

Abstract: A  message  packet  transmitter  for  transmitting  a packet of electronic data signals onto a communication network  without  interruption.  A  first-in,  first-out electronic  memory  has  a  transmit  state  in  which  an electronic data signal  stored therein is output.   The electronic memory has an idle state in which electronic data signals stored therein are not output.
